CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a National Stage of PCT/US11/035361 filed May 5,2011 and claims the benefit of priority under 35 U.S.C. § 119(e) fromU.S. Provisional Application Serial No. 61/331,609, filed May 5, 2010,the entire contents of which is hereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to compositions comprising at least oneacrylic thickener. Among other improved or beneficial properties,compositions containing an acrylic thickener have surprisingly goodremoval properties.

DISCUSSION OF THE BACKGROUND

Many cosmetic compositions, including pigmented cosmetics such asfoundations, concealers, lipsticks, and mascaras, and other cosmetic andsunscreen compositions, have been formulated in an attempt to possesgood feel and texture upon application. Unfortunately, many of thesecompositions can be difficult to apply and do not possess a soft textureor smooth feel upon application. Moreover, such compositions oftentimeshave a tendency to feel tacky, yielding poor application andspreadability characteristics, and can be difficult to remove.

Silicone elastomers have been added to cosmetic compositions to improvethe feel of the compositions. However, the use of silicone elastomerscan be problematic, given their expense and that they can be difficultto formulate owing to their chemical make up—for example, compositionsincluding silicone elastomers can be unstable, particularly ifuncomplimentary compounds are added to an elastomer-containingcomposition.

Thus, there remains a need for improved cosmetic compositions havingimproved cosmetic properties, particularly good feel and texturecharacteristics upon application, without relying solely (if at all)upon silicone elastomers, and which can be easily removed.

Accordingly, one aspect of the present invention is a care and/or makeupand/or treatment composition for keratinous material which has goodcosmetic properties such as, for example, good feel and/or textureproperties upon application, and/or good removability.

SUMMARY OF THE INVENTION

The present invention relates to compositions comprising at least oneacrylic thickener. Preferably, the compositions are anhydrous.

The present invention also relates to colored compositions comprising atleast one coloring agent and at least one acrylic thickener. Suchcolored compositions can be, for example, cosmetic compositions such aslip compositions (for example, lipstick or liquid lip colors), mascaras,eyeshadows or foundations. Preferably, the compositions are anhydrous.

The present invention also relates to methods of treating, caring forand/or making up keratinous material (for example, skin, eyes, eyelashesor lips) by applying compositions of the present invention comprising atleast one acrylic thickener, preferably anhydrous compositions, to thekeratinous material in an amount sufficient to treat, care for and/ormake up the keratinous material.

The present invention also relates to methods of enhancing theappearance of keratinous material (for example, skin, eyes, eyelashes,or lips) by applying compositions of the present invention comprising atleast one acrylic thickener, preferably anhydrous compositions, to thekeratinous material in an amount sufficient to enhance the appearance ofthe keratinous material.

The present invention also relates to methods of volumizing eyelashescomprising applying a mascara composition of the present inventioncomprising at least one acrylic thickener, preferably an anhydrousmascara composition.

It is to be understood that both the foregoing general description andthe following detailed description are exemplary and explanatory only,and are not restrictive of the invention.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the expression “at least one” means one or more and thusincludes individual components as well as mixtures/combinations.

Other than in the operating examples, or where otherwise indicated, allnumbers expressing quantities of ingredients and/or reaction conditionsare to be understood as being modified in all instances by the term“about,” meaning within 10% to 15% of the indicated number.

“Film former” or “film forming agent” as used herein means a polymer orresin that leaves a film on the substrate to which it is applied, forexample, after a solvent accompanying the film former has evaporated,absorbed into and/or dissipated on the substrate.

“Transfer resistance” as used herein refers to the quality exhibited bycompositions that are not readily removed by contact with anothermaterial, such as, for example, a glass, an item of clothing or theskin, for example, when eating or drinking. Transfer resistance may beevaluated by any method known in the art for evaluating such. Forexample, transfer resistance of a composition may be evaluated by a“kiss” test. The “kiss” test may involve application of the compositionto human keratin material such as hair, skin or lips followed by rubbinga material, for example, a sheet of paper, against the hair, skin orlips after expiration of a certain amount of time following application,such as 2 minutes after application. Similarly, transfer resistance of acomposition may be evaluated by the amount of product transferred from awearer to any other substrate, such as transfer from the hair, skin orlips of an individual to a collar when putting on clothing after theexpiration of a certain amount of time following application of thecomposition to the hair, skin or lips. The amount of compositiontransferred to the substrate (e.g., collar, or paper) may then beevaluated and compared. For example, a composition may be transferresistant if a majority of the product is left on the wearer's hair,skin or lips. Further, the amount transferred may be compared with thattransferred by other compositions, such as commercially availablecompositions. In a preferred embodiment of the present invention, littleor no composition is transferred to the substrate from the hair, skin orlips.

“Long wear” compositions as used herein, refers to compositions wherecolor remains the same or substantially the same as at the time ofapplication, as viewed by the naked eye, after an extended period oftime. Long wear properties may be evaluated by any method known in theart for evaluating such properties. For example, long wear may beevaluated by a test involving the application of a composition to humanhair, skin or lips and evaluating the color of the composition after anextended period of time. For example, the color of a composition may beevaluated immediately following application to hair, skin or lips andthese characteristics may then be re-evaluated and compared after acertain amount of time. Further, these characteristics may be evaluatedwith respect to other compositions, such as commercially availablecompositions.

“Substituted” as used herein, means comprising at least one substituent.Non-limiting examples of substituents include atoms, such as oxygenatoms and nitrogen atoms, as well as functional groups, such as hydroxylgroups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylenegroups, polyoxyalkylene groups, carboxylic acid groups, amine groups,acylamino groups, amide groups, halogen containing groups, ester groups,thiol groups, sulphonate groups, thiosulphate groups, siloxane groups,and polysiloxane groups. The substituent(s) may be further substituted.

“Volatile”, as used herein, means having a flash point of less thanabout 100° C.

“Non-volatile”, as used herein, means having a flash point of greaterthan about 100° C.

“Anhydrous” means the compositions contain less than 1% water.Preferably, the compositions of the present invention comprising the atleast one acrylic thickener contain no water.

The compositions discusses below may be in any form, either liquid ornon-liquid (semi-solid, soft solid, solid, etc.). For example, they maybe a paste, a solid, a gel, or a cream. They may be an emulsion, such asan oil-in-water or water-in-oil emulsion, a multiple emulsion, such asan oil-in-water-in-oil emulsion or a water-in-oil-in-water emulsion, ora solid, rigid or supple gel. The compositions of the invention may, forexample, comprise an external or continuous fatty phase. Thecompositions can also be a molded composition or cast as a stick or adish.

Depending on the intended application, such as a stick, hardness of thecomposition may also be considered. The hardness of a composition may,for example, be expressed in gramforce (gf). The composition of thepresent invention may, for example, have a hardness ranging from 20 gfto 2000 gf, such as from 20 gf to 900 gf, and further such as from 20 gfto 600 gf.

This hardness is measured in one of two ways. A first test for hardnessis according to a method of penetrating a probe into the composition andin particular using a texture analyzer (for example TA-XT2i from Rheo)equipped with an ebonite cylinder of height 25 mm and diameter 8 mm. Thehardness measurement is carried out at 20° C. at the center of 5 samplesof the composition. The cylinder is introduced into each sample ofcomposition at a pre-speed of 2 mm/s and then at a speed of 0.5 mm/s andfinally at a post-speed of 2 mm/s, the total displacement being 1 mm.The recorded hardness value is that of the maximum peak observed. Themeasurement error is ±50 gf.

The second test for hardness is the “cheese wire” method, which involvescutting an 8.1 mm or preferably 12.7 mm in diameter stick compositionand measuring its hardness at 20° C. using a DFGHS 2 tensile testingmachine from Indelco-Chatillon Co. at a speed of 100 mm/minute. Thehardness value from this method is expressed in grams as the shear forcerequired to cut a stick under the above conditions. According to thismethod, the hardness of compositions according to the present inventionwhich may be in stick form may, for example, range from 30 gf to 300 gf,such as from 30 gf to 250 gf, for a sample of 8.1 mm in diameter stick,and further such as from 30 gf to 200 gf, and also further such as from30 gf to 120 gf for a sample of 12.7 mm in diameter stick.

The hardness of the composition of the present invention may be suchthat the compositions are self-supporting and can easily disintegrate toform a satisfactory deposit on keratin materials. In addition, thishardness may impart good impact strength to the inventive compositions,which may be molded or cast, for example, in stick or dish form.

The skilled artisan may choose to evaluate a composition using at leastone of the tests for hardness outlined above based on the applicationenvisaged and the hardness desired. If one obtains an acceptablehardness value, in view of the intended application, from at least oneof these hardness tests, the composition falls within preferredembodiments of the invention.

As defined herein, stability is tested by placing the composition in acontrolled environment chamber for 8 weeks at 25° C. In this test, thephysical condition of the sample is inspected as it is placed in thechamber. The sample is then inspected again at 24 hours, 3 days, 1 week,2 weeks, 4 weeks and 8 weeks. At each inspection, the sample is examinedfor abnormalities in the composition such as phase separation if thecomposition is in the form of an emulsion, bending or leaning if thecomposition is in stick form, melting, or syneresis (or sweating). Thestability is further tested by repeating the 8-week test at 25° C., 37°C., 45° C. and under freeze-thaw conditions. A composition is consideredto lack stability if in any of these tests an abnormality that impedesfunctioning of the composition is observed. The skilled artisan willreadily recognize an abnormality that impedes functioning of acomposition based on the intended application.

The cosmetic compositions and methods of the present invention cancomprise, consist of, or consist essentially of the essential elementsand limitations of the invention described herein, as well as anyadditional or optional ingredients, components, or limitations describedherein or otherwise useful in personal care.

Experiment Results

Effect of Water-sensitive Material on Removability

Mascaras were applied on fake lashes and dried for 1 hour. Then the fakelashes were immersed into water for 15 minutes. For 0% water sensitivematerial formula (control), mascara remained on the fake lashes and thewater was clear. Similar results were found for the compositioncontaining 5% Polysorbate 80. For the formula containing 7.5% Simulgel,mascara was partially removed into the water. For the formularepresentative of the invention having 5% Viscup-EZ, an even betterremovability was found: a higher % of mascara swelled into water andformed tube shape.

Demonstration of Tube Removal

Mascara was applied on fake lashes and dried for 1 hour. Then the fakelashes were immersed into water for 15 minutes. Subsequently the mascarawas removed by a cotton pad and tubes were observed on the pad.
